itunes play songs backwards

since a few versions, iTunes plays songs backwards. if I click on a full disk, played in order. But if for example I click on the fifth track on a disc, the next song that plays is the fourth, then the third, etc.

What I can do? ITunes and reinstalled several times and even over versions this issue is still not disappear.

Its not a problem of my computer because I have found many similar discussion topics in this forum, and none has been resolved. Why Apple is ignoring this problem?
